What material is dx51d?

dx51d galvanized sheet material, which is mainly a non-ferrous alloy composed of zinc as a matrix and other elements. The main alloy elements are aluminum, copper, magnesium and so on. Zinc alloy has low melting point, good fluidity, easy plastic processing and welding, and resistance to atmospheric corrosion. According to the manufacturing process is divided into cast zinc alloy and deformation zinc alloy, commonly used cast zinc alloy is zinc aluminum copper magnesium alloy, its casting process performance is good, cooling speed has less impact on mechanical properties, more used in the manufacture of mechanical parts, toys, decorations, household appliances and so on. Commonly used deformed zinc alloys are zinc-aluminum alloy and zinc-copper alloy. The former contains 4% to 15% aluminum, in order to improve the strength and hardness of the alloy, but also a small amount of copper, magnesium and other alloying elements. Its strength is high, easy to form, can replace some brass or hard aluminum manufacturing precision forgings. The latter is the copper content of 0.7% to 1.5%, copper can increase the alloy strength and impact toughness, and reduce plasticity. Zinc-copper alloy is suitable for making daily hardware products or replacing some brass.
